Multi-step form in Laravel - php

Question

I am trying to create a multi-step form for a user to fill after logging in. I created separate pages with forms that will be a part of the common form.
The data will be saved in the "users" table.
I am new to Laravel and I followed this: https://www.5balloons.info/multi-page-step-form-in-laravel-with-validation/
In my FormController I have these methods:
public function index(Request $request)
{
$request->session()->forget('user');
$user = User::all();
return view('form.index',compact('user',$user));
}
public function updateStep1(Request $request)
{
$user = $request->session()->get('user');
return view('form.update-step1',compact('user', $user));
}
public function postupdateStep1(Request $request)
{
$validatedData = $request->validate([
'first_name' => 'required',
]);
if(empty($request->session()->get('user'))){
$user = User::where('id',auth()->user()->id)->first();
$user->fill($validatedData);
$request->session()->put('user', $user);
}else{
$user = $request->session()->get('user');
$user->fill($validatedData);
$request->session()->put('user', $user);
}
return redirect('/form/update-step2');
}
public function updateStep2(Request $request)
{
$user = $request->session()->get('user');
return view('form.update-step2',compact('user', $user));
}
public function postupdateStep2(Request $request)
{
$validatedData = $request->validate([
'address' => 'required',
]);
if(empty($request->session()->get('user'))){
$user = User::where('id',auth()->user()->id)->first();
$user->fill($validatedData);
$request->session()->put('user', $user);
}else{
$user = $request->session()->get('user');
$user->fill($validatedData);
$request->session()->put('user', $user);
}
return redirect('/form/store');
}
public function store(Request $request)
{
$user = User::where('id',auth()->user()->id)->first();
$user = $request->session()->get('user');
$user->save();
return redirect('/form');
}
And these are the Routes:
Route::get('/form', 'FormController#index');
Route::get('/form/update-step1', 'FormController#updateStep1');
Route::post('/form/update-step1', 'FormController#postupdateStep1');
Route::get('/form/update-step2', 'FormController#updateStep2');
Route::post('/form/update-step2', 'FormController#postupdateStep2');
Route::post('/form/store', 'FormController#store');
This is the first part of the form:
#extends('layouts.app')
#section('content')
<h1>update - Step 1</h1>
<form action="/form/update-step1" method="post">
#csrf
<div class="form-group">
<label for="name">First Name</label>
<input type="text" value="{{ old('first_name', $user->first_name ?? null) }}" class="form-control" name="name">
</div>
#if ($errors->any())
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
<button type="submit" class="btn btn-primary">Continue</button>
</form>
#endsection
I get an error when I try to submit, saying that the fields are required. So even if I do enter a name etc., it doesn't work. If I delete the validations, it seems like everything works but no data is added to the database.
Any suggestions?

You should use the input name is first_name because you have used first_name in the validation.
<input type="text" value="{{ old('first_name', $user->first_name ?? null) }}" class="form-control" name="first_name">
OR
If want to change name value in the user table:
FormController
$validatedData = $request->validate([
'name' => 'required',
]);
first part of the form:
<input type="text" value="{{ old('name', $user->name ?? null) }}" class="form-control" name="name">
